In the process of smelting iron and steel, molten iron contains a large amount of impurities, particularly excessive silicon, sulfur, phosphorus and other harmful elements to influence the hot-metal reaction, in order to ensure the quality of the molten iron and the requirements of subsequent production, the molten iron needs to be subjected to desulfurization treatment, the impurities in the molten iron are separated out and float on the surface of the molten iron after the desulfurization treatment, slag skimming is carried out on molten iron slag on the surface of the molten iron, and only the slag skimmed molten iron can be added into a converter. The lower the sulfur content requirement is, the higher the corresponding required slag removal cleanliness is, and in order to reduce the slag carrying amount of molten iron as much as possible and meet the requirement of subsequent production, the application provides a desulfurization slag removal method for a desulfurization hot-metal ladle, which can ensure the qualification rate of desulfurization slag removal of the desulfurization hot-metal ladle.
The implementation details of the technical solutions of the embodiments of the present application are described in detail below:
referring to fig. 1, fig. 1 is a flowchart of a desulfurization slagging-off method of a desulfurization hot-metal bottle according to an embodiment of the present application.
According to an exemplary embodiment of the present application, there is provided a desulfurization slagging-off method of a desulfurization hot-metal bottle, the method including the steps S1 to S3 as follows:
step S1, before the slag skimming arm carries out slag skimming and after each slag skimming return of the slag skimming arm, acquiring molten iron surface images in the desulfurization molten iron tank.
In this application, after the molten iron reaches the desulfurization hot-metal bottle, carry out the desulfurization in the desulfurization hot-metal bottle, after carrying out the desulfurization to the molten iron slag can float on the surface of molten iron, need control the slagging-off arm and carry out a lot of and take off the sediment to reduce the area sediment volume on molten iron surface, make the molten iron purer and satisfy the demand of follow-up production.
In the application, the molten iron surface image in the desulfurization molten iron tank is obtained before the slag skimming arm skims slag, and the molten iron surface image in the desulfurization molten iron tank is obtained after each slag skimming return of the slag skimming arm, wherein the molten iron surface image can comprise the molten iron surface area in the desulfurization molten iron tank.
S2, preprocessing the molten iron surface image to obtain an effective image, extracting edges of the effective image, and calculating the total area of the bright surface in the effective image, wherein the total area of the bright surface is the total area of the molten iron surface without molten iron slag.
In this application, after the molten iron surface image is acquired, due to the environment of image acquisition, there may be some irrelevant areas in the acquired molten iron surface image, so that in order to ensure that the acquired images all include only the image of the molten iron surface area, the molten iron surface image needs to be preprocessed, and an effective image is obtained by setting the ROI area. After the effective image is obtained, the effective image needs to be analyzed to distinguish areas without iron slag and areas with iron slag in the effective image, the effective image can be subjected to edge extraction to distinguish areas without iron slag and areas with iron slag in the effective image, the areas without iron slag in the effective image are brighter than the areas with iron slag, the areas without iron slag present bright surfaces, and the areas with iron slag present dark surfaces.
In the application, after edge extraction is performed on the effective image, the total area of a bright surface in the effective image can be calculated, namely the total area of molten iron surface without molten iron slag in the effective image can be calculated, the slag skimming progress can be reflected through the total area of the bright surface obtained through each slag skimming calculation, and the larger the total area of the bright surface is, the less molten iron slag on the molten iron surface is indicated, and the better the quality of molten iron is.
And S3, judging that desulfurization slag skimming is qualified when the total area of the bright surface reaches a preset area and the difference value between the total area of the bright surface and the total area of the bright surface calculated by the last slag skimming is lower than a preset area threshold value.
In the application, when the slag raking arm carries out slag raking each time, statistics recording is carried out on the total area of the bright surface with the largest surface of molten iron after slag raking, when the bright surface area reaches the preset area, and the difference value between the total area of the bright surface and the total area of the bright surface calculated by the last slag raking operation carried out by the slag raking arm is lower than the preset area threshold value, the desulfurization slag raking operation is judged to be qualified, and the slag raking operation is not required to be continued.
In one embodiment of the present application, preprocessing the molten iron surface image includes:
and removing an invalid region in the molten iron surface image by carrying out Gaussian filtering processing and binarization processing on the molten iron surface image.
In the method, when the molten iron surface image is preprocessed, gaussian filtering and binarization can be adopted to process the molten iron surface image so as to remove invalid areas in the molten iron surface image, influence of a few irrelevant factors can be avoided, and accuracy of judging whether desulfurization slag skimming is qualified or not is ensured.
In one embodiment of the present application, before the edge extraction is performed on the effective image, the method further includes:
and acquiring component information of molten iron in the desulfurization molten iron tank, and determining an edge extraction gray threshold according to the component information, wherein the edge extraction gray threshold is used for distinguishing areas without molten iron slag from areas with molten iron slag in the effective image.
In the application, before the effective image is subjected to edge extraction, component information of molten iron in the desulfurization molten iron tank can be obtained, the component information can be steel grade information, and the component information, the heat number and other information of the molten iron can be obtained through a three-level network before slag skimming. Since the composition of molten iron is different, the brightness of the areas containing molten slag and not containing molten slag in the obtained molten iron surface image will be different according to the composition of molten iron, so that an edge extraction gray threshold value needs to be determined according to the composition information of molten iron, and the edge extraction gray threshold value can be used for distinguishing the areas containing no molten slag and no molten slag in the effective image so as to calculate the total area of the bright surface in the effective image.
In this application, it should be noted that, when the area without the iron slag and the area with the iron slag in the effective image are distinguished, the edge gray threshold may be determined according to the component information of the molten iron, the area without the iron slag and the area with the iron slag in the effective image may be distinguished, for example, after the component information of the molten iron is obtained, the edge extraction threshold is determined according to the component information to be 150, the luminance of the surface of the molten iron may be in the range of 0 to 255, the area without the iron slag and the area with the iron slag in the effective image may be distinguished according to the edge extraction threshold 150, the area with the luminance greater than the edge extraction threshold 150 is a bright surface (the area without the iron slag in the effective image), and the area with the luminance greater than the edge extraction threshold 150 is a dark surface (the area with the iron slag in the effective image). After the areas without the molten iron slag and the areas with the molten iron slag in the effective image are distinguished, pixels of the areas without the molten iron slag and the areas with the molten iron slag in the effective image can be calculated, if the areas of the areas without the molten iron slag in the effective image are calculated, pixels of a bright surface in the effective image (the pixels can be understood as the number of points of the image and the total amount of the pixels can also be the area of the reaction image) can be calculated, and the total amount of the pixels of the bright surface in the effective image, namely the area of the bright surface in the effective image, can be calculated.
In this application, it should be noted that in a general case, when the total area of the bright surfaces reaches a preset area, it may be determined that desulfurization and slagging is acceptable, but due to the variability of factors such as steelmaking environment, if after the first slagging of the slagging arm, the bright surface area obtained by the fourth slagging calculation is 98, though the bright surface area obtained by the fourth calculation may already satisfy the desulfurization and slag is acceptable, strong exposure may occur on site, so that the obtained molten iron surface image is in a bright state as a whole, the bright surface area in the effective image (the area of the area without molten slag in the effective image) is obtained by edge extraction and calculation, assuming that the bright surface area obtained by the first calculation is 50, the bright surface area obtained by the second slagging calculation is 61, and the bright surface area obtained by the third slagging calculation is 72.
In this application, in order to avoid the above-mentioned problem, a preset area threshold may be set, if when the total area of the bright surface reaches the preset area and the difference between the total area of the bright surface and the total area of the bright surface calculated by the last slag skimming is lower than the preset area threshold, the desulfurization slag skimming is judged to be qualified, and the method is used to judge and verify whether the desulfurization slag skimming is qualified, so that the interference caused by other factors is avoided, and the judgment of the desulfurization slag skimming to be qualified is inaccurate. For example, setting an area threshold to be 13, assuming that the bright surface area obtained by the first calculation is 50, the bright surface area obtained by the calculation after the second slag skimming is 61, the bright surface area obtained by the calculation after the third slag skimming is 72, the bright surface area obtained by the calculation after the fourth slag skimming is 98, if the bright surface total area reaches a preset area during the fourth slag skimming, but the difference value between the bright surface total area of the fourth time and the bright surface total area obtained by the calculation after the third slag skimming is higher than the preset area threshold (13), judging that the desulfurization slag skimming is not qualified, and continuing the next slag skimming until the bright surface total area reaches the preset area and the difference value between the bright surface total area and the bright surface total area obtained by the calculation after the last slag skimming is lower than the preset area threshold, and judging that the desulfurization slag skimming is qualified.
In the method, after the slag raking arm withdraws after slag raking, obtaining a molten iron surface image in a desulfurization molten iron tank, preprocessing the molten iron surface image to obtain an effective image, extracting edges of the effective image, calculating the total area of a bright surface in the effective image, carrying out statistics recording on the total area of the bright surface calculated each time, forming a linear curve of a slag raking area, and judging whether slag raking is qualified by combining the change rate of the slag raking area curve when the total area of the bright surface reaches a preset area, namely judging whether desulfurization slag raking is qualified when the difference value between the total area of the bright surface and the total area of the bright surface calculated last time is lower than a preset area threshold value.
In one embodiment of the present application, the method further comprises:
when the desulfurization and slag skimming are judged to be qualified, the alarm device is controlled to send out a voice prompt, and information at least comprising post shift, slag skimming starting time, slag skimming ending time, slag skimming time and slag skimming furnace number is recorded.
In one embodiment of the application, when the molten iron surface image is preprocessed, a Pyqt5 editing program application interface can be used for displaying various parameters of the molten iron surface image processing picture and the image processing in real time, so that the processing process is visualized in a data mode, and production conditions can be monitored by post personnel in real time conveniently.
In this application, when judging desulfurization and slagging-off is qualified, recognition program can send signal control peripheral hardware alarm device (can be stereo set) and send the pronunciation and remind to remind post personnel, avoid the slagging-off to be qualified still carry out the slagging-off operation, lead to extravagant production time and increase the loss of taking off the slag plate. When desulfurization and slag skimming are qualified, information at least comprising post shift, slag skimming starting time, slag skimming ending time, slag skimming furnace number and the like can be recorded, so that subsequent historical data can be conveniently inquired and analyzed, a data source can be provided for subsequent production information settlement inquiry, and the production operation plan can be conveniently guided.
In one embodiment of the present application, an image of the surface of molten iron in a desulphurized hot metal tank is acquired by an imaging device.
In one embodiment of the application, the resolution of the image capturing device for capturing the surface image of the molten iron in the desulphurized molten iron tank is 1080p.
